As someone about to become an RB user, I have acquired a dual cable release. The claim is that it will send up the mirror first and then drop the shutter. The way I see it, if that is true my FOV would only be interrupted for a few seconds and the vibration from the shutter in the lens would be minimal.
Now, I have modified a grip to accept this release instead of the provided button and lever at the bottom. Has anyone had any experiences with this sort of cable release and the RB?
